Application and. m 15, 1912. Serial in. 709,571.

To all whom it may concern 9 Be it known that T, Trrorras E. UNKS, acitizen of the United States of America, re-

siding at Sanduslry, in the county of Erie and State of Uhio, haveinvented certain new and useful improvements in Gearing, of which thefollowing is a specification.

This invention relates to certain new and usefi'il improvements inwashing machines, and the primary object of the invention is to providean improved machine of this type in which the rub-board is perforatedand is maintained stationary, while the tub is given alternating rotaryand vertical movement, to effect squeezing of the clothes and passage ofthe water through the rubboard when the tub is moved upwardly, and upondownward movement of the tub to form a partial vacuum between the tuband rub-board whereby the water is crawn through the rub-board withgreat force, thereby causing same to pass through the clothes.

In the drawings: Figure 1 is a top plan view of the invention; Fig. 2 isa side elevation; Fig. 3 is a top plan view with the tub removed; F ig.1 is a longitudinal sectional view of Fig. 8; Fig. is an enlargedfragmentary detail view, partly in section of one end of the rub-boardsupporting bar and the holding means thereof; and Fig. 6 is a similarview of the opposite end of said bar and the holding means thereof. Fig.7 is an elevation of one of the cam-shaped gears.

The frame of the machine is preferably formed of angle-bars andcomprising the vertical legs 1, and horizontal connecting members 2. Ahorizontal plate 3 is connected to the frame and has a central bearing 1and end bearings 5 and 6 secured to its upper face. An idler segmentalgear 7 is loosely mounted on a stub shaft 8 that is journaled in bearing5 and one end of central bearing 4, and a similar segmental operatinggear 9 is keyed to an operating shaft 10 that is journaled in theotherend of the central bearing 1 and the end bearing 6. A master gearwheel 11 meshes with the segmental gears 7 and 9 and has pins 12 on itsupper face for engagement in apertures, provided for the receptionthereof, in the bottom of the tub 13. The master gear wheel 11 has ashaft 1 1 secured thereto and depending therefrom, the shaft beingslidingly received in openings provided therefor in the plate 3, and inthe base of the central bearing 4. A coil spring 15 encircles the lowerend of shaft 1&1 and at its upper end abuts the under. face of the plate3, while its lower end carries a bearing 16 upon which the shaft 1 1rests. The function of the spring being to exert upward pressure on thetub to assist the operator in raising the tub and contents andpreventing a jerking movement when the tub is on the downward movementalso equalizing the amount of energy required in the upward and downwardmovement.

When movement is imparted to the segmental gears through the mechanismhereinafter described, a combined oscillating and vertical movement isimpartedto the tub. This is accomplished by gears 7 and 9 which areformed cam shape. As said gears are in mesh and in contact with themaster gear wheel which is in turn attached to the tub, a rotarymovement is transmitted to the tub by the gear teeth and at the sametime the tub is forced upward by one of the cam shape gears as shown inFig. 1 dotted line. The tub is forced to descend by its own gravity andthe tension of the spring 15 when the cam shape gears 7 and 9 movedownwardly.

Shaft 10 has a socketed member 17 attached thereto to receive the handoperated lever 18, by means of which latter the shaft 10 is givenoscillatory movement. A short arm 19 is formed integral with member 17and has one end of a connecting rod 20 pivoted thereto, the opposite endof which rod 20 is pivoted to a crank-1i in 21 of a gear wheel 22mounted in a bearing 23 that is connected to the frame. The gear wheel22 meshes with a pinion 2 1 that is connected to a fly wheel 25, the flywheel and pinion thereof being mounted on a shaft that is journaled in abearing 26 secured to the frame.

The rub-board 27 is perforated as depicted in Fig. 1 of the drawings andis adjustably suspended from a vertical rod 28 that is 'secured to across bar 29 by means of a clamp 30. One end of the cross bar 29 isformed of T-shape in cross section as shown in Fig. 5 of the drawings,and has the leg of the T received in an opening 31 that is formed in aplate 32 secured to the upper end of one of the legs 1 of the frame. Theplate 32 is formed with a hook-shaped member 33 that overlies the crossbar 29 in spaced relation thereto. The opposite end of the cross bar 29is forked as shown at 34 in Fig. 6 and receives the leg of a T-shapedmember 35 that is formed on a plate 36 secured to the leg 1 of the framethat is diagonally opposite to the leg which has plate 32 attachedthereto.

What is claimed is: 1. In a device of the type set mounted thereon, anoperating shaft having a cam shaped'segmental gear also mounted on theframe and rigidly connected to sald shaft, a master gear in mesh withboth of,

said segmental gears, a spring held shaft depending therefrom, a memberconnected to the operating shaft, a hand lever con nected to saidmember, said member having a depending arm, a gear wheel, a connectingrod connected at its ends to said arm and said last named wheel, and afly wheel having a pinion in mesh with said last named gear wheel; saidmechanism being adapted to impart a combined oscillating and verticalmovement to the spring held shaft.

Copies of this patent may be obtained for five cents each, by addressingforth, a; frame, an idler cam shaped segmental gear' a 2. In a device ofthe type set forth,a frame, an idler segmental gear journaled on theframe,'an operating shaft having a segmental gear rigidly connectedtherewith, a

' master gear in mesh with both of said segmental gears and having aspring held shaft depending therefrom, a member connected to the"operating shaft, a fly-wheel, and means to operate said fly-wheel fromsaid member; said mechanism being adapted to impart a combined verticaland oscillating movement to the spring held shaft.

- 3. In a device of the type set forth, a vertically movable spring heldmaster gear,

and means in mesh with said gear for supn the Commissioner of Patents,
